it has a power inverter on it, charges from lighter(ithink but never used this way) or ac outlet, also has a light, jumper cables and an inflator. Inflator is for kids toys only wont work on tires. Lasts all day so you dont have to keep on and off so that laptop battery doenst give up.
Why the 116, cuz i want to see if i can get more out of the t3 settings ive never tried. The only drawback to using these is octane. Bg's site said these setttings require 116 octane. I know i will have more kr if i dont use the higher octane......just following directions.
